Perhaps you should try some spelling variations:
thuc dan » thuc hanh, hoc dan, thuc vat
dang van » hoang van, hang va
te sach » toc sach
thuc va » thuc vat, thuc day
ve cham » va cham, ve chat, vu cham
hieu ve » hieu va, hieu van
lang xa » lang ha, dang xay, lang van
cua tuc » cua duc, cua tu, cua thuoc
vi cua » vai cua, di cua

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: te sach y ((lang xa) OR (dang van)) hoi. hieu ve cham ((thuc va) OR (thuc dan)) hanh vi cua tuc~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach y ((lang xa) or (dang van)) hoi. hieu ve cham ((thuc va) OR (thuc dan)) hanh vi cua tuc~".
• Adding a wildcard symbol may retrieve word variants: te sach y ((lang xa) or (dang van)) hoi. hieu ve cham ((thuc va) OR (thuc dan)) hanh vi cua tuc*.
